    That’s cool! QR codes are awesome stuff in these days.
    Plenty of free sites are available for generating QR codes and my favorite too is http://generator.onbarcode.com/online-qr-code-barcode-generator.aspx.

    Often, I would check the message encoded in QR code before I use it. You see, accuracy does matters a lot.
    Try this free QR code reader: http://www.onbarcode.com/scanner/qrcode.html. It do help me a lot.
